摘要: 为了探明中国南方缺硼水稻田中增施硼肥在水稻上的应用效果,通过田间小区试验,研究了硼肥不同施用方法及不同用量的组合对南方早稻的生长期、分蘖状况、剑叶叶绿素含量、水稻生物量及水稻产量的影响。结果表明,基施硼肥和基施配合叶面喷施硼肥均能提早水稻生育期,尤其是齐穗期,比CK提前了1~3天;基施硼肥或基施配合叶面喷施硼肥均促进水稻分蘖,有利于提高稻叶叶绿素含量和生物量积累,起到水稻增产的效果,其中常规施肥 基施持力硼11.25 kg/hm2和常规施肥 基施持力硼7.5 kg/hm2 喷施速乐硼0.45 kg/hm2综合效果最好,值得在南方水稻生产中推广应用。

Abstract: The aim of this study is to explore the effect of boron fertilizer application on rice in boron deficiency soil in south China. Using field plot test, effects of different boron fertilizer application methods and amounts on the growth period, tillering, chlorophyll content of flag leaf, biomass and yield of rice were analyzed. The results showed that the basal application of boron fertilizer and combination of basal application and foliar application of boron fertilizer could make rice growth period early, especially full heading stage which was 1-3 days earlier. And they could also accelerate tillering, increase chlorophyll content of flag leaf, rice biomass and yield. In conclusion, conventional fertilization basal application of 11.25 kg/hm2 boron fertilizer and conventional fertilization basal application of 7.5 kg/hm2 boron fertilizer foliar application of 0.45 kg/hm2 boron fertilizer had relative better effect, and are worthy of popularization and application in rice production in south China.
